Definitions

  • the present invention pertains to plastic fasteners and more particularly to plastic, button-type fasteners which may be secured to material without the use of threads or stitching and a method of securing such plastic fasteners to material.
  • Fasteners of the button or stud type for insertion in a buttonhole in a garment to fasten two pieces thereof together are widely utilized.
  • Such fasteners conventionally are disc-shaped with a central portion having a plurality of apertures therein for receiving thread which is stitched into the material to secure the fastener thereto.
  • the use of threads in securing buttontype fasteners to material has the disadvantage of requiring intricate and costly apparatus for automatic stitching in the home and in industry; and, furthermore, threads have a tendency to fray and loosen thereby requiring frequent replacement of the button-type fasteners.
  • buttontype fasteners The'frequent loss and replacement of buttontype fasteners is a source of constant bother to the housewife especially since the threads are subject to great tensile forces when the two pieces of the garment are separated without properly pushing the button-type fastener through the buttonhole.
  • Another disadvantage in the use of threads for securing button-type fasteners is that tensile stress on the threads tends to crinkle thin, synthetic, lightweight materials.
  • the disadvantages of conventional, thread-secured, button-type fastener that may be secured to material without the use of threads.
  • buttonstype fasteners of a nature to permit their simple an easy securing to material to not only aid the housewife in replacing such fasteners and in initially securing such fasteners to homemade garments but also to facilitate the securing of such fasteners to mass produced garments.
  • All previous attempts to overcome the disadvantages of securing fasteners to material with thread have failed in that they normally require a securing step tantamount to that of stitching. That is, attempts to overcome the disadvantages of using thread to secure button-type fasteners have centered around the continued use of conventional button-type fasteners with changed securing means, such as crimpable nylon filaments.
  • some sort of securing element must be inserted through the apertures in thefastener and the material; and, accordingly, the disadvantages of time consuming attachment and the requirement of threading have not been obviated.
  • button-type fasteners must be capable of being formed in a myriad of sizes, shapes and colors in order that they may be matched with the many materials utilized in garments, that fasteners of this type must be secured to material in a manner such that the material is not damaged, that the securing of such fasteners to material must be an extremely simple step to permit full utilization throughout industry as well as by housewives, and that such fasteners must be firmly secured to the material to avoid inadvertent loss.
  • the present invention is generally characterized in a plastic, single component, button-type fastener having a button portion, a neck portion extending from the button portion, and tapered stem portion having a pointed end and an end connected with the neck portion and having a greater width than the neck portion to define an undercut whereby the stem portion may be inserted through material to capture the material in the undercut.
  • Another object of the present invention is to construct a button-type fastener that has a stem for insertion through material without damaging the material.
  • a further object of the present invention is to secure a plastic, button-type fastener to material by flattening a stem of the fastener and then partially shearing the flattened stem to destroy the memory of the plastic.
  • the present invention has another object in that a button-type fastener has a tapered stem and a neck portion forming an undercut to capture material to which the fastener is to be secured.
  • a further object of the present invention is to shape a plastic, single component, button'type fastener such that the fastener may be cold-headed to firmly grasp material to which the fastener is to be secured without rubbing.
  • buttons-type fastener of the present invention can by secured to material without threads or threading, that the button-type fastener can be easily secured to material with a hand tool and without the use of heat, that the button-type fastener has great strength and is firmly-secured, and that the button-type fastener is suitable for use with mass produced garments.
  • FIG. 1 is a side elevation of a button-type fastener according to the present invention.
  • FIG. 2 is a side elevation of the button-type fastener of FIG. 1 in alignment with an attaching tool after attachment of the fastener to a piece of material.
  • FIG. 3 is an enlarged section of the attached buttontype fastener of FIG. 2.
  • FIG. 1 A button-type fastener according to the present invention is illustrated in FIG. 1 and is preferably formed as a single component of a plastic material, such as nylon.
  • Fastener 10 has an annular button portion 12 having an outer face 14, a planar inner face 16 joined by an arcuate edge 18, and a cylindrical collar 20 centrally disposed on inner face 16 and having a diameter smaller than the diameter of the flat portion of inner face 16.
  • a slender, cylindrical neck portion 22 extends coaxially from a flat upper surface 24 of collar 20 to a conical stem 26 which tapers to a pointed end 28.
  • Stem 26 has a flat lower surface 30 which is in parallel with upper surface 24 of collar 20 to define a annular undercut 32 for receiving material to which fastener 10 is to be secured.
  • pointed end 28 is positioned adjacent the desired location of fastener 10 on the material. By applying a slight pressure to the fastener, pointed end 28 pierces the material, and the fastener is then forced through the material until the material snaps into undercut 32. It should be appreciated that the tapered shape of stem 26 permits the fastener to be self-piercing and thereby obviates the use of an additional piercing element such as the needle required to pull thread through material.
  • Tool 34 includes a stationary cylindrical pressure block 36 which has an upper end 38 adapted to be secured to any suitable force transmitting member such as the movable handle of a plier-like hand tool and a slightly concave pressure surface 40 adapted to engage stem 26.
  • a cylindrical shearing sleeve 42 is coaxially 'and slidably mounted around pressure block 36 and has an inner surface 44 acting as a shearing edge and a flat annular pressure surface 46. Shearing sleeve 42 is adapted to be operatively attached to the force transmitting member to move individually in relation to pressure block 36.
  • the cold-heading of stem 26 is a two-step process.
  • Pressure block 34 is first forced against stem 26 such that concave pressure surface 40 quickly smashes the stem into a flattened, slightly convex form, and thereafter shearing sleeve 42 is moved axially along pressure block 36 against the flattened stem.
  • Shearing sleeve 42 is moved past pressure surface 40 of pressure block 42 to complete the forming of a securing head for the fastener in a manner such that annular pressure surface 46 forms an outer rim 48 for the securing head.
  • Outer rim 48 surrounds a central protrusion 50 formed by the partial shearing action of inner surface 44 against the flattened stem as the leading edge of inner surface 44 moves past concave pressure surface 40.
  • the shearing action destroys the memory of the plastic and sets or stress relieves the cold-formed head.
  • the cold-heading of stem 26 causes neck 22 to bulge and assume a barrel-like shape 52 to more firmly contact the material in annular undercut 32. Furthermore, the pressure during cold-heading forces outer rim 48 of the cold-formed head toward upper surface 24, as shown at 54, to decrease annular undercut 32 and firmly grasp the material. This is extremely advantageous in that it prevents movement of fastener 10 with respect to the material to thereby prevent fraying of the material from rubbing against the fastener. Accordingly, it can be seen that the fastener of the present invention is prevented from inadvertent loss.
  • the sheared edge 56 of central protrusion 50 is formed relatively slowly with respect to the initial smashing of stem 26 such that radial cold flow is permitted to form the head and to completely destroy the memory of the plastic.
  • the surface of fastener 10 prior to cold-heading, as shown in FIG. 1, is uniquely responsible for the strength of the attached fastener and the ease with which the fastener is secured to material.
  • the pointed end 28 permits initial piercing of the material without severing the threads, and the tapered shape of stem 26 allows the stem 26 to be fully inserted without damage to the material.
  • the tapered shape of stem 26 also facilitates flattening of the stem since the pointed end does not exhibit a great resistance to change thereby increasing the ease with which the fastener may be secured to material.
  • the annular undercut 32 permits the material to snap back to its initial form and be captured around neck 22.
  • the lower surface 30 of stem 26, which eventually forms outer rim 48, is aligned with the upper surface 24 of collar 20 such that pressure during cold-heading is evenly distributed, and the diameters of upper surface 24 of collar 20 and lower surface 30 of stem 26 are much greater than the diameter of neck 22 to provide a substantial undercut 32.
  • the diameter of collar 20 is small enough to be received in a buttonhole, and outer surface 14 of button portion 12 may have any desired shape or design for aesthetic appeal.
  • a one-piece plastic button for button holes on garment material and the like comprising a button portion having a first width and having rounded edges adapted for easy insertion and removal during a buttoning movement, I
  • a collar extending from said button portion and having a second width less than said first width and having an upper surface for contacting one side of a material
  • a head portion having a tapered stem portion extending from said neck portion for insertion through the material and being deformed into top and lower surfaces with an outer rim therebetween,
  • said outer rim being displaced toward said collar causing the material to be firmly grasped between the upper surface of said collar and the lower surface of said head portion whereby movement of said neck portion and said upper and lower sur- 5 Sald head pomon' faces is precluded relative to the material.
